The truckers are NOT protesting against the vaccine itself, and if you believe that they are, I would highly encourage you to find different sources for news.
The truckers are protesting the idea that the government can force them to take the vaccine against their will.
I would hope that people could find some more common ground on this, since there is an almost identical debate happening around the idea of bodily autonomy:
Almost nobody, or functionally/practically nobody, is "pro abortion". People who are "pro choice" are saying that they don't believe the government should be able to force women to carry a child until birth, because they believe it violates their right to bodily autonomy.
The truckers are saying the same thing. They aren't "anti vaccine", they are against the government forcing them to take a vaccine, because they believe it violates their right to bodily autonomy.
